Description
Technical Field
[0001] This invention relates to the field of valve technology, and in particular to a new energy valve. Background Technology
[0002] An electric valve is a device that uses an electric actuator to control the valve, thereby controlling its opening and closing. It can be divided into two parts: the upper part is the electric actuator, and the lower part is the valve.
[0003] In related technologies, electric valves have a larger operating torque than ordinary valves. The opening and closing speed of electric valves can be adjusted. They have a simple structure, are easy to maintain, and can be used to control the flow of various types of fluids, such as air, water, steam, various corrosive media, mud, oil, liquid metals, and radioactive media.
[0004] However, during the process of controlling the opening and closing of the valve, the sealing element used to seal the valve is in a state of tension for a long time when the valve is closed. The sealing element is prone to failure due to fatigue. When the sealing element fails, it cannot seal the valve in the closed state, which can easily lead to production accidents. Moreover, the process of replacing the sealing element is cumbersome and complicated, making it difficult to repair and replace the sealing element of electric valves. Summary of the Invention

[0015] Optionally, in the above-mentioned new energy valve, the thickness of the slider is less than the thickness of the guide groove.
[0016] Optionally, in the above-mentioned new energy valve, the connection between the flexible passive seal and the fixed plate is located on the side of the fixed plate facing the through hole, and the connection between the flexible passive seal and the fixed plate is covered by the fixed plate.

[0022] The above-described one or more technical solutions provided by this invention can have the following advantages or at least achieve the following technical effects:
[0023] This invention proposes a new energy valve that reduces the contact area between the valve plate's outer sealing sleeve and the fluid in the valve body through a passive sealing component. When the valve plate is in its initial position, the passive sealing component is in a natural state; it only becomes taut when the valve plate is in the closed position. This reduces fatigue of the passive sealing component, increases its service life, and extends the maintenance and replacement cycle. Maintenance and replacement of the sealing sleeve and passive sealing component are performed through a disassembly port, simplifying the process and improving efficiency. Furthermore, when the sealing sleeve fails, the passive sealing component can partially seal the gap between the valve plate and the through-hole, reducing fluid leakage in the horizontal chamber and providing production time during production processes even with a failed sealing sleeve, thus ensuring the production cycle continues.

[0039] The inventive concept of the present invention will be further explained below with reference to some specific embodiments.
[0040] This invention proposes a new energy valve.
[0041] Reference Figure 1 and Figure 2 , Figure 1 This is a partial internal structure diagram of the new energy valve of the present invention; Figure 2 This is a schematic diagram of the structure of the new energy valve of the present invention.
[0042] In one embodiment of the present invention, such as Figure 1 and Figure 2 As shown, a new energy valve includes a valve body 100, an electric actuator 300, a valve plate 400, and a passive sealing assembly 500. The valve body 100 has a horizontal chamber 110 and a vertical chamber 120. The bottom end of the vertical chamber 120 communicates with the horizontal chamber 110. A partition 200 is detachably installed in the horizontal chamber 110, dividing it into an inlet chamber 111 and a drain chamber 112. A through hole 130 extending circumferentially along the horizontal chamber 110 is formed on the partition 200, connecting the inlet chamber 111 and the drain chamber 112. The electric actuator 300 is located at the top of the valve body 100. The electric actuator 300 has two vertical ends: a free end and a connecting end. The free end is vertically movable within the vertical chamber 120, and the connecting end connects to an external solar power source. The electrical module is connected; the valve plate 400 is housed in the valve body 100, and a sealing sleeve is provided around the valve plate 400; the free end is connected to the valve plate 400, and the electric actuator 300 is used to drive the valve plate 400 to reciprocate between the working position of abutting against the door body to close the through hole 130 and the initial position of being housed in the vertical chamber 120 to open the through hole 130; the passive sealing assembly 500 is installed on the partition 200 at the position corresponding to the through hole 130; the passive sealing assembly 500 includes a fixed end and a movable end, the fixed end is connected to the partition 200 near the vertical chamber 120, the movable end is slidably disposed on the partition 200, and a flexible passive sealing element 530 is disposed between the fixed end and the movable end, the flexible passive sealing element 530 is used to press against the valve plate 400 and the partition 200 when the valve plate 400 is in the working position.
[0043] It should be noted that the electric actuator 300 includes an automatic control system and a piston-type electric cylinder as in the prior art, and the piston rod 310 of the piston-type electric cylinder is the free end of the electric actuator 300; the solar power supply module is a prior art and has a photovoltaic module, an energy storage module and a power supply interface, which is connected to the power interface at the connection end of the electric actuator 300; the sealing sleeve covers the entire surface of the valve plate 400 and fills the gap between the valve plate 400 and the through hole 130 when the valve plate 400 is in the working position, and the valve plate 400 can achieve an interference fit with the inner wall of the horizontal chamber 110 through the sealing sleeve; the flexible passive seal 530 is a flexible rubber strip as in the prior art; the working position refers to the position where the valve plate 400 is in the horizontal chamber 110 and the through hole 130 is closed, and the initial position refers to the position when the valve plate 400 is housed in the vertical chamber 120, that is, the position of the valve plate 400 when the liquid inlet chamber 111 and the liquid outlet chamber 112 are connected.
[0044] It should be understood that during the reciprocating movement of the valve plate 400 driven by the electric actuator 300 between the working position abutting against the door body to close the through hole 130 and the initial position housed in the vertical chamber 120 to open the through hole 130, the rubber sealing sleeve fitted around the valve plate 400 is repeatedly squeezed, and the sealing sleeve is continuously stretched against the outer surface of the valve plate 400. Furthermore, the sealing sleeve comes into contact with the fluid in the horizontal chamber 110, inevitably causing material fatigue and failure of the sealing sleeve. During the process of the valve plate 400 being driven by the electric actuator 300 from the initial position to the working position, the valve plate 400's... The bottom end contacts and abuts against the movable end of the passive sealing assembly 500. The valve plate 400 drives the movable end of the passive sealing assembly 500 to slide downwards away from the fixed end of the passive sealing assembly 500, so that the flexible passive seal 530 connected between the movable end and the fixed end of the passive sealing assembly 500 is stretched. This causes the flexible passive seal 530 to fill the gap at the junction of the vertical side of the valve plate 400 and the through hole 130, reducing the contact area between the sealing sleeve and the fluid in the horizontal chamber 110, thereby improving the service life of the sealing sleeve. Furthermore, the flexible passive seal 530 itself... The flexible passive seal 530 improves the sealing performance of the valve plate 400 to the through hole 130, providing a certain production time for the production process under the condition of seal sleeve failure. The flexible passive seal 530 can replace the seal sleeve to partially seal the gap between the valve plate 400 and the through hole 130, reducing the amount of fluid leakage in the horizontal chamber 110 and ensuring the production cycle. During the process of the valve plate 400 being driven by the electric actuator 300 to move from the working position to the initial position, the valve plate 400 tends to disengage from the moving end of the passive sealing assembly 500 due to its upward movement. The flexible passive seal 530, due to its own deformation capacity, i.e., elasticity, can effectively prevent this. After the movable end of the passive sealing assembly 500 is separated from the valve plate 400, the flexible passive seal 530 returns to its natural state from the stretched state, avoiding material fatigue caused by the flexible passive seal 530 being constantly stretched and taut, thus ensuring the service life of the flexible passive seal 530 and ensuring the sealing effect of the valve plate 400 on the through hole 130. When the passive sealing assembly 500 needs to be repaired or replaced, the partition 200 can be removed from the horizontal chamber 110. This improves the service life of the sealing sleeve and the passive sealing assembly 500 while making the sealing sleeve and sealing assembly easy to repair and replace.
[0045] The technical solution of this invention reduces the contact area between the outer sealing sleeve of the valve plate 400 and the fluid in the valve body 100 by using a passive sealing component 500. When the valve plate 400 is in the initial position, the passive sealing component 500 is in a natural state. The passive sealing component 500 is only in a taut state when the valve plate 400 is in the closed position, thereby reducing the fatigue of the passive sealing component 500, improving the service life of the passive sealing component 500 and the sealing sleeve, and extending the maintenance and replacement cycle of the sealing sleeve and the passive sealing component 500. The sealing sleeve and the passive sealing component 500 can be maintained and replaced through the disassembly port 113, making the maintenance and replacement process simple and easy to operate, improving the maintenance and replacement efficiency of the sealing sleeve and the passive sealing component 500. Moreover, when the sealing sleeve fails, the passive sealing component 500 can replace the sealing sleeve to partially seal the gap between the valve plate 400 and the through hole 130, reducing the amount of fluid leakage in the horizontal chamber 110, providing a certain amount of production time for the production process under the condition of sealing sleeve failure, and ensuring the production cycle.
[0046] Continue to refer to Figure 1 and Figure 2 and refer to Figure 4 , Figure 4 This is a schematic diagram of the limiting strip involved in the present invention.
[0047] Furthermore, such as Figure 1 , Figure 2 and Figure 4 As shown, a disassembly port 113 is formed on the side wall of the horizontal chamber 110 corresponding to the position of the partition 200, and the disassembly port 113 extends radially along the horizontal chamber 110; the partition 200 is inclined on one side with the through hole 130, and a limiting strip 600 is connected to the side of the partition 200 away from the through hole 130, and the limiting strip 600 is slidably disposed in the disassembly port 113.
[0048] It should be noted that a disassembly port 113 is formed on the side wall of the horizontal chamber 110. A limiting strip 600 is slidably provided in the disassembly port 113. The limiting strip 600 is connected to the partition 200. The partition 200 is not connected to the inner wall of the horizontal chamber 110. That is, the partition 200 is limited in the horizontal chamber 110 only by the limiting strip 600.
[0049] It should be understood that when the passive sealing assembly 500 needs to be repaired or replaced, the partition 200 can be pulled out of the horizontal chamber 110 by the limiting strip 600 to repair or replace the passive sealing assembly 500, making the repair and replacement process of the passive sealing assembly 500 easier to achieve.
[0050] It is worth noting that a sealing ring is provided at the junction of the limiting strip 600 and the disassembly port 113 to prevent fluid in the horizontal chamber 110 from flowing out through the disassembly port 113.
[0051] Continue to refer to Figure 1 and Figure 2 and refer to Figure 3 , Figure 3 This is a schematic diagram of the passive sealing assembly involved in the present invention.
[0052] Furthermore, such as Figures 1 to 3 As shown, the partition 200 is recessed downwards at the position corresponding to the through hole 130 to form a guide groove 210, and the opening of the guide groove 210 communicates with the through hole 130; the passive sealing assembly 500 includes a fixed plate 510 and a slider 520, the slider 520 forming a movable end, the fixed plate 510 forming a fixed end, the slider 520 being slidably disposed in the guide groove 210, the fixed plate 510 being connected to the partition 200, the fixed plate 510 being connected to one end of the flexible passive seal 530, and the slider 520 being connected to the other end of the flexible passive seal 530, and both the fixed plate 510 and the slider 520 extending radially along the horizontal chamber 110; the electric actuator 300 is also used to drive the valve plate 400 to move the slider 520 downwards along the guide groove 210 to stretch the sealing position of the flexible passive seal 530, and to drive the valve plate 400 upwards away from the slider 520 to release the flexible passive seal 530.
[0053] It should be noted that the partition 200 is not a completely circular structure. The edge of the outer contour of the partition 200 includes a straight section and an arc-shaped section. The straight section of the partition 200 is the part that forms the through hole 130, and the arc-shaped section of the partition 200 is the part that fits into the inner wall of the horizontal chamber 110. In the straight section of the partition 200, the through hole 130 is moved away from the bottom of the horizontal chamber 110 towards the top of the horizontal chamber 110.
[0054] It should be understood that the straight section of the partition 200 is recessed downward to form a guide groove 210 that extends in the same direction as the straight section. A slider 520 is slidably disposed within the guide groove 210. The sliding engagement between the slider 520 and the guide groove 210 is the sliding engagement between a slide rail and the slider 520 in the prior art. During the process of the valve plate 400 being driven by the electric actuator 300 to move from the initial position to the working position, the bottom end of the valve plate 400 contacts and abuts against the slider 520. The valve plate 400 drives the slider 520 to slide downward along the guide groove 210 in a direction away from the fixed plate 510, so that the flexible passive seal 530 connecting the fixed plate 510 and the slider 520 is stretched, so that the flexible passive seal 530 fills the junction of the vertical side of the valve plate 400 and the through hole 130. The gap reduces the contact area between the sealing sleeve and the fluid in the horizontal chamber 110, thereby improving the service life of the sealing sleeve. Furthermore, the flexible passive seal 530 itself improves the sealing performance of the valve plate 400 to the through hole 130. During the process of the valve plate 400 being driven by the electric actuator 300 from the working position to the initial position, the upward movement of the valve plate 400 tends to disengage from the slider 520. Because the flexible passive seal 530 has its own deformation capacity (i.e., elasticity), after the slider 520 disengages from the valve plate 400, the flexible passive seal 530 returns to its natural state from a stretched state. This avoids material fatigue caused by the flexible passive seal 530 being constantly stretched and tensile, ensuring the service life of the flexible passive seal 530 and thus ensuring the sealing effect of the valve plate 400 to the through hole 130.
[0055] It should be understood that, under conditions of irregular maintenance, since the failure time of the sealing sleeve on the valve plate 400 is uncertain, when the sealing sleeve on the valve plate 400 is in a failed state, the flexible passive seal 530 can replace the sealing sleeve to partially seal the gap between the valve plate 400 and the through hole 130, reduce the amount of fluid leakage in the horizontal chamber 110, provide a certain amount of production time for the production process under the condition of sealing sleeve failure, and ensure the production cycle.
[0056] Furthermore, the thickness of the slider 520 is less than the thickness of the guide groove 210.
[0057] It should be noted that, in order to ensure that the flexible passive seal 530 can be filled into the guide groove 210 under the action of the slider 520 to seal the gap between the valve plate 400 and the through hole 130, the thickness of the slider 520, i.e., the material thickness of the slider 520 in the radial direction of the horizontal chamber 110, must be less than the thickness of the guide groove 210, i.e., the material thickness of the guide groove 210 in the radial direction of the horizontal chamber 110. This ensures that when one end of the flexible passive seal 530 is stretched by the slider 520, the flexible passive seal 530 tends to move into the guide groove 210, thereby achieving the sealing effect.
[0058] Continue to refer to Figure 3 .
[0059] Furthermore, such as Figure 3 As shown, the connection between the flexible passive seal 530 and the fixed plate 510 is located on the side of the fixed plate 510 facing the through hole 130, and the connection between the flexible passive seal 530 and the fixed plate 510 is covered by the fixed plate 510.
[0060] It should be noted that, in order to ensure the sealing effect of the flexible passive seal 530 on the gap at the junction between the valve plate 400 and the through hole 130, and to ensure the connection stability of the flexible passive seal 530 itself, one end of the flexible passive seal 530 is completely wrapped around the periphery of the fixing plate 510. Since the fixing plate 510 is located at the edge of the through hole 130 and there is no gap between the fixing plate 510 and the hole wall of the through hole 130, the width of the flexible passive seal 530 can be extended to the junction of the through hole 130 and the valve plate 400 to seal the through hole 130 when closed.
[0061] It should be understood that the surface of the fixed plate 510 is recessed inward to form multiple columnar holes. When replacing the flexible passive seal 530, the flexible passive seal 530 is melted by heat fusion, and then the melted flexible passive seal 530 to be replaced is removed from the fixed plate 510. Then, molten rubber is injected into the columnar holes using a mold to form a new flexible passive seal 530. The operation of replacing the flexible passive seal 530 is simple, making the flexible passive seal 530 easy to maintain. Moreover, the columnar holes provide sufficient connection area for the flexible passive seal 530, ensuring that when the end of the flexible passive seal 530 connected to the slider 520 is stretched by the slider 520, the flexible passive seal 530 will not come off the fixed plate 510, thus ensuring the sealing effect of the flexible passive seal 530 between the valve plate 400 and the through hole 130.
[0062] Continue to refer to Figures 1 to 4 and refer to Figure 5 , Figure 5 This is a schematic diagram of the protrusion involved in the present invention.
[0063] Furthermore, such as Figures 1 to 5 As shown, the bottom wall of the horizontal chamber 110 forms a limiting groove 114 corresponding to the position of the valve plate 400; the valve plate 400 includes a connecting part 410 and a limiting part 420. The connecting part 410 is connected to the free end, and the limiting part 420 is connected to the connecting part 410. The limiting part 420 is used to abut against the inner wall of the limiting groove 114 when the valve plate 400 is in the working position.
[0064] It should be noted that, in order to ensure that the flexible passive seal 530 has sufficient stretch range when stretched to ensure that the flexible passive seal 530 can seal the gap between the through hole 130 and the valve plate 400, and to ensure that the valve plate 400 can be accurately and stably in the working position when the through hole 130 is closed, a limiting groove 114 is formed by the downward recess of the inner wall of the horizontal chamber 110 relative to its connection with the vertical chamber 120.
[0065] It should be understood that the bottom wall of the through hole 130 is located above the limiting groove 114, that is, the only part of the valve plate 400 that directly abuts against the valve plate 400 is its connecting part 410. In other words, the stretching range of the flexible passive seal 530 only covers the abutting part of the connecting part 410 and the through hole 130, so as to prevent the valve plate 400 from excessively stretching the flexible passive seal 530 and causing the material of the flexible passive seal 530 to fail due to fatigue.
[0066] It is worth noting that the inner wall of the through hole 130 is tapered from top to bottom in the vertical direction, and the connecting part 410 has a tapered structure adapted to it, so as to ensure that the flexible passive seal 530 can fit tightly against the lateral inner wall of the through hole 130 when stretched, so as to seal the abutment gap between the through hole 130 and the valve plate 400 together with the sealing sleeve, thereby improving the service life of the sealing sleeve.
[0067] Furthermore, the limiting part 420 is provided with a protrusion 421 on the side facing the horizontal chamber 110 for abutting against the slider 520.
[0068] It should be noted that, in order to ensure that the gap between the connecting part 410 and the through hole 130 can be covered by the flexible passive seal 530, a protrusion 421 for abutting against the slider 520 is provided on the limiting part 420 at the lower end of the connecting part 410. In this embodiment, the groove length of the groove is greater than the height of the connecting part 410, so that after the limiting part 420 abuts against the slider 520 through the protrusion 421, it can drive the slider 520 to be located below the bottom end of the connecting part 410, so that the stretched flexible passive seal 530 can completely fill the gap between the side of the connecting part 410 and the through hole 130.
[0069] It should be understood that, in order for the protrusion 421 to have the condition to abut against the slider 520, the protrusion 421 includes a branch section and a radial extension section. The radial extension section extends radially along the horizontal chamber 110, and the branch section is used to extend the extension section to the limiting part 420 to compensate for the displacement difference of the slider 520 in the vertical direction, so that the stretching range of the flexible passive seal 530 can be greater than the abutment range between the side of the connecting part 410 and the through hole 130.
[0070] Furthermore, the limiting groove 114 is a U-shaped groove, and the limiting part 420 has a U-shaped structure that is adapted to the limiting groove 114.
[0071] It should be noted that, in order to prevent the limiting part 420 from puncturing the flexible passive seal 530 when it abuts against the slider 520, the limiting part 420 has a U-shaped structure. In order to prevent the through hole 130 from communicating with the limiting groove 114 and flowing through the limiting groove 114 when the valve plate 400 is in the working position to block the through hole 130, the limiting groove 114 is a U-shaped groove adapted to the valve plate 400.
[0072] It should be understood that both the connecting part 410 and the limiting part 420 are covered with sealing sleeves. When the limiting part 420 abuts against the limiting groove 114, the limiting part 420 seals the limiting groove 114 through the sealing sleeves. Specifically, although the position where the protrusion 421 is provided cannot seal the opening of the limiting groove 114, since the protrusion 421 is not provided at the edge of the protrusion 421, the outer contour of the limiting groove 114 can still be covered by the sealing sleeve, thereby sealing the outer contour of the limiting groove 114.
[0073] Furthermore, the electric actuator 300 includes a piston rod 310, which is disposed in the vertical chamber 120. The piston rod 310 forms a free end, and the bottom end of the piston rod 310 is connected to the valve plate 400. A sealing ring 700 is sleeved at the connection between the valve plate 400 and the piston rod 310.
[0074] It should be noted that, in order to prevent fluid in the horizontal chamber 110 from entering the vertical chamber 120 and affecting the service life of the electric actuator 300, a sealing ring 700 is provided at the connection between the valve plate 400 and the piston rod 310.
[0075] Furthermore, a guide ring 121 is embedded in the inner wall of the vertical chamber 120. The guide ring 121 is sleeved around the piston rod 310, and the distance between the guide ring 121 and the horizontal chamber 110 is greater than the height of the valve plate 400.
[0076] It should be noted that, in order to ensure that the valve plate 400 can accurately abut against the moving end of the passive sealing assembly 500, a guide ring 121 is provided in the vertical chamber 120, which is sleeved and slidably engaged with the piston rod 310.
[0077] It should be understood that the guide ring 121 is used to reduce the vibration of the piston rod 310 during movement, so that the valve plate 400 connected to the bottom end of the piston rod 310 has a stable movement process, thereby ensuring the normal operation of the passive sealing assembly 500.
[0078] Finally, it should be noted that the sequence numbers of the above embodiments of the present invention are for descriptive purposes only and do not represent the superiority or inferiority of the embodiments.
